摘要： Disclosed is a method for measuring a parameter of interest from a target and associated apparatuses. The method comprises obtaining measurement acquisition data relating to measurement of a target on a production substrate during a manufacturing phase; obtaining a calibration correction database and/or a trained model having been trained on said calibration correction database, operable to correct for effects in the measurement acquisition data; correcting for effects in the measurement acquisition data using first correction data from said calibration correction database and/or using said trained model so as to obtain corrected measurement data and/or a corrected parameter of interest which is/are corrected for at least said effects; and updating said calibration correction data and/or said trained model with said corrected measurement data and/or corrected parameter of interest.

摘要： A dark field metrology device includes an objective lens arrangement and a zeroth order block to block zeroth order radiation. The objective lens arrangement directs illumination onto a specimen to be measured and collects scattered radiation from the specimen, the scattered radiation including zeroth order radiation and higher order diffracted radiation. The dark field metrology device is operable to perform an illumination scan to scan illumination over at least two different subsets of the maximum range of illumination angles; and simultaneously perform a detection scan which scans the zeroth order block and/or the scattered radiation with respect to each other over a corresponding subset of the maximum range of detection angles during at least part of the illumination scan.

摘要： Disclosed is an illumination system for delivering incoherent radiation to a metrology sensor system. Also disclosed is an associated metrology system and method. The illumination system comprises a spatial filter system for selective spatial filtering of a beam of said incoherent radiation outside of a module housing of the metrology sensor system. At least one optical guide is provided for guiding the spatially filtered beam of incoherent radiation to the metrology sensor system, the at least one optical guide being such that the radiation guided has a substantially similar output angle as input angle.

摘要： In an alignment sensor of a lithographic apparatus, position sensing radiation is delivered to a target (P1). After reflection or diffraction from the target, position sensing radiation is processed to determine a position of the target. Reference radiation interferes with the position sensing radiation) while a relative phase modulation is applied between the reference radiation and the position sensing radiation. The interfering radiation includes a time-varying component defined by the applied phase modulation. The interfering radiation is delivered to two photodetectors in such a way that each photodetector receives said time-varying component in anti-phase to that received at the other photodetector. A difference signal (i(t)) from said photodetectors contains an amplified, low noise version of said time-varying component. This is used in determining the position of the target. Mode matching enhances interference. Surface scattered radiation is rejected.

摘要： Disclosed is a method of determining a correction for a measurement of a target and an associated apparatus. The measurement is subject to a target-dependent correction parameter which has a dependence the target and/or a stack on which the target is comprised. The method comprises obtaining first measurement data relating to a measurement of a fiducial target, said first measurement data comprising at least a first and second set of intensity parameter values: and second measurement data relating to a measurement of the fiducial target, the second measurement data comprising a third set of intensity parameter values. A target-invariant correction parameter is determined from said first measurement data and second measurement data. the target-invariant correction parameter being a component of the target-dependent correction parameter which is not dependent on the target and/or a stack: and the correction is determined from said target-in-variant correction parameter.

摘要： The system includes a radiation source, a diffractive element, an optical system, a detector, and a processor. The radiation source generates radiation. The diffractive element diffracts the radiation to generate a first beam and a second beam. The first beam includes a first non-zero diffraction order and the second beam includes a second non-zero diffraction order that is different from the first non-zero diffraction order. The optical system receives a first scattered beam and a second scattered radiation beam from a target structure and directs the first scattered beam and the second scattered beam towards a detector. The detector generates a detection signal. The processor analyzes the detection signal to determine a target structure property based on at least the detection signal. The first beam is attenuated with respect to the second beam or the first scattered beam is purposely attenuated with respect to the second scattered beam.

摘要： A method for a metrology process, the method includes obtaining first measurement data relating to a first set of measurement conditions and determining a first measurement recipe based on the first measurement data. At least one performance indicator is determined from one or more components of the first measurement data obtained from a component analysis or statistical decomposition. Alternatively, at least one performance indicator is determined from a comparison of one or more first measurement values relating to the first measurement recipe and one or more second measurement values relating to a second measurement recipe, where second measurement recipe is different to the first measurement data and relates a second set of measurement conditions, the second set of measurement conditions being different to the first set of measurement conditions.

摘要： A metrology system includes a radiation source, first, second, and third optical systems, and a processor. The first optical system splits the radiation into first and second beams of radiation and impart one or more phase differences between the first and second beams. The second optical system directs the first and second beams toward a target structure to produce first and second scattered beams of radiation. The third optical system interferes the first and second scattered beams at an imaging detector. The imaging detector generates a detection signal based on the interfered first and second scattered beams. The metrology system modulates one or more phase differences of the first and second scattered beams based on the imparted one or more phase differences. The processor analyzes the detection signal to determine a property of the target structure based on at least the modulated one or more phase differences.

摘要： Disclosed is a metrology device (1600) configured to produce measurement illumination comprising a plurality of illumination beams, each of said illumination beams being spatially incoherent or pseudo-spatially incoherent and comprising multiple pupil points in an illumination pupil of the metrology device. Each pupil point in each one of said plurality of illumination beams has a corresponding pupil point in at least one of the other illumination beams of said plurality of illumination beams thereby defining multiple sets of corresponding pupil points, and the pupil points of each set of corresponding pupil points are spatially coherent with respect to each other.
